NOT_MASK

Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Performs a bit to bit negation of an integer value

Inputs

IN  : ANY Integer input

Outputs

Q : ANY     Bit to bit negation of the input

Remarks

Arguments can be signed or unsigned integers from 8 to 32 bits.

In FFLD language, the input rung (EN) enables the operation, and the output rung keeps the same value as the input rung. In IL "Instruction list" This is a low-level language and resembles assembly language, the parameter (IN) must be loaded in the current result before calling the function.

ST Language

Q := NOT_MASK (IN);

FBD Language

FFLD Language

(* The function is executed only if EN is TRUE *)
(* ENO is equal to EN *)

IL Language:

Op1: LD "Ladder diagram" Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them       IN
